Anti-Slip Stair Nosings & Edge Painting
Stairs are a major slip and fall hazard. Anti-slip nosings and correct edge painting keep people safe while meeting AS 1428.1 luminance contrast requirements.

What is Safer Stairs Save Lives?
Quick answer: Line Marking Australia installs anti-slip stair nosings and paints stair edges so every step is easy to see and grip. Nosings give a contrasting strip 50 to 75 mm wide with at least 30% luminance contrast under AS 1428.1:2021, and a textured surface rated for slip resistance under AS 4586:2013. We fit carborundum, aluminium or coating options.
Stair falls cause more serious injuries in buildings than almost any other incident type. Many falls happen because people can't see step edges clearly or the surface is too slippery.
Anti-slip stair nosings address both problems. The contrasting colour makes edges visible (meeting AS 1428.1 luminance contrast requirements). The textured surface provides grip (meeting AS 4586 slip resistance requirements).
We install various nosing types depending on your stairs and traffic. Carborundum-filled epoxy for extreme grip. Aluminium with anti-slip inserts for durability. Applied coatings for budget-conscious options.
A factory in Dandenong had three lost-time injuries from stair falls in one year. Their concrete stairs were all one colour with no edge marking or anti-slip treatment. We installed carborundum nosings with high-contrast yellow colour. Zero stair injuries in two years since.
We made an error on a Ringwood office building in 2019. We used a nosing strip with insufficient luminance contrast, about 20% instead of the required 30%. It looked fine but failed testing during building inspection. We replaced all nosings at our cost, around $2,200. Now we verify contrast before completion.
Standards for stair nosings in Australia
AS 1428.1:2021 asks for a strip 50 to 75 mm wide across the full width of each tread at the nosing, with a luminance contrast of at least 30% against the rest of the step. Slip resistance is tested and rated under AS 4586:2013, and the National Construction Code sets the minimum rating for stair treads and nosings. In workplaces, the Model WHS Regulations require you to manage slip and trip risks.

Frequently Asked Questions
Depends on traffic, environment, and budget. Industrial stairs often need carborundum. Commercial buildings suit aluminium. We assess and recommend the right product.
Yes, surface-applied nosings can be mechanically fixed or adhesive-bonded to existing concrete, timber, or metal stairs.
Quality nosings typically last 5-15 years depending on traffic. High-traffic industrial stairs wear faster than occasional-use office stairs.
Outdoor stairs need weather-resistant nosings and often higher slip resistance for wet conditions. We specify appropriate products.
Minimal. Keep them clean and replace when worn. Aluminium nosings with inserts can have just the insert replaced when worn.
Paint provides luminance contrast but limited slip resistance. For safety-critical stairs, nosings are recommended. Paint may suit low-traffic internal stairs.
A stair nosing strip should be 50 to 75 mm wide and run the full width of the tread under AS 1428.1:2021. The strip must have at least 30% luminance contrast against the rest of the step so people with low vision can see each edge. Line Marking Australia checks contrast before signing off the job.
Usually yes. Line Marking Australia can do one side of the stairs at a time, or work after hours and on weekends, so the building stays open. Mechanically fixed aluminium nosings can be used straight away, while epoxy-bonded and carborundum nosings need a short cure time before full foot traffic.
